Key Features
The Intel® Ethernet Network Adapter E810-2CQDA2 delivers up to 200Gbps of total bandwidth in PCIe 4.0-compliant systems¹. Each QSFP28 port supports up to 100Gbps, providing the functionality and throughput of two 100Gbps adapters in a single bifurcated PCIe 4.0 x16 slot.
Performance for Cloud Applications
Delivers the bandwidth and increased application throughput required for demanding cloud workloads including edge services, web servers, database applications, caching servers, and storage targets.
Provides packet classification and sorting optimizations for high-bandwidth network and communications workloads, including mobile core, 5G RAN, and network appliances.
As modern data centers scale, a key challenge is to provide scalable, predictable application-level performance. ADQ technology improves performance scalability and predictability by dedicating queues to key workloads, delivering predictable high performance through dramatically reduced jitter.
- Dual-Port QSFP28
- PCI Express (PCIe) 4.0 x16
- Ethernet Port Configuration Tool (EPCT)
- Application Device Queues (ADQ)
- Dynamic Device Personalization (DDP)
- Supports both RDMA iWARP and RoCEv2
